After WW2, the US largely designed the new world order for its own benefit. It became the world's arms dealer, the US dollar became the world's reserve currency and it had effective control of the world's financial system. And the US got very rich from all of this and wielded a lot of power.
The US has done more to destroy the system it designed and benefits from in the last 1.5 years than at any time since 1945.
What this entire fiasco is about is China. China is the new superpower. It threatens the American global hegemony because it can't be bullied. Why is China the new Big Bad? To sell weapons. Pretty much the entire of American foreign policy is about selling weapons.
So Liberation Day was a ham-fisted way to try and isolate and bring to heel China. It has failed spectacularly because the dumbest sychophants imaginable are in charge of this administration. Because while doing all this, we're witnessing a lootocracy on the largest scale ever seen. When Trump took office in 2017, the national debt was ~$16T and it had taken ~200 years to get there. It just got over $40T. That's like $2T in interest payments every year just to service the debt.
Long ter bond yields keep going higher. That's going to be a really big problem, particularly because there's a political desire to lower interest rates. That's ismply not going to happen and record-high inflation is going to continue, if not get worse, all while real wages stagnate or decline.
So the US can't economically compete with China. Well, it can't militarily compete either. The US has been deceisively been totally defeated by Iran, an absolutely pointless war of choice. And they think they can bully China? Get the hell out of there. Part of the problem is the (now) $1t+ in annual military budget is just more looting from government coffers.
Empires don't die slowly or quietly. That's really what's happening here. The seeds of destruction for the Gulf security architecture have been sown. While Europe is still an American vassal state, realization is growing that the status quo cannot continue. Unfortunately I suspect a fascist takeover will happen long before Europe divests itself from the US protection racket.
I believe that the late 2020s will be written about in history books as the beginning of the end of American empire.
